Flexible pressure sensor with high sensitivity and fast response for electronic skin using near-field electrohydrodynamic direct writing

Tannery solid waste-derived cross-scale deformable piezoresistive sensors for monitoring human body motions

“…Compared with the previously reported piezoresistive sensors that exhibited high sensitivity in a low-pressure range (Fig. 3b), 22–40 our piezoresistive sensor provides high sensitivity in a quite wide sensory range. In addition, another linear relationship between Δ I/I 0 and applied pressure P was also observed in the pressure range of 3.08–28.85 kPa, with a sensitivity of 0.48 kPa −1 .…”

A multifunctional electronic skin based on patterned metal films for tactile sensing with a broad linear response range

“…The performance of our device was compared with other existing resistive pressure/temperature sensors with a broad linearity range of pressure detection (see table S1). Our pressure sensor outperforms most of existing resistive sensors (32)(33)(34)(36)(37)(38) with regard to the linear response range, the sensitivity, and the maximum sensing range but perform comparable response/recovery time. Our temperature sensor has a similar performance with existing resistive sensors.…”
